On Monday at Kings County Supreme Court in Brooklyn, New York a former math teacher at Saint Ann’s School in Brooklyn Heights pleaded guilty to use of a child in a sexual performance as a sexually motivated felony and five counts of endangering the welfare of a child.
Winston Nguyen, 38, of Harlem, New York, a former math teacher at Saint Ann’s School in Brooklyn Heights pretended to be a young teen and fellow student when engaging in conversations of a sexual nature over the messaging application Snapchat between October 2022 and May 2024, when the victims were between the ages of 13 and 15 years old.
The Brooklyn DA’s Office said Nguyen used two Snapchat accounts, hunterkristoff and haircutbongos, to contact the victims. Those two Snapchat accounts, the Brooklyn DA’s Office, said were connected to IP addresses associated with Nguyen, including his Harlem residence. Other evidence included digital communications and images and accounts from victims.
The Brooklyn DA’s Office said Nguyen sent nude images and videos that depicted a teenage boy masturbating to the victims. The defendant also used the accounts to engage in prolonged conversations that described and depicted various sexual acts and got the victims to send images and videos of the victims engaged in sexual performance to him through the Snapchat accounts.
Nguyen pleaded guilty before Kings County Supreme Court Justice Phillip Tisne to one count of use of a child in a sexual performance as a sexually motivated felony, and five counts of endangering the welfare of a child. He was charged with crimes against six children who went to various elite independent schools in Brooklyn.
Nguyen’s plea of guilty is in exchange for a promised sentence of seven years in prison, 10 years’ post-release supervision, and sex offender registration.
Nguyen will be back in court for sentencing on March 17, 2025.
